1. A plasticizer composition comprising, based on 100 parts by weight of the plasticizer composition,
35 to 50 parts by weight of a terephthalate-based compound represented by the following Chemical Formula 1,
30 to 55 parts by weight of a cyclohexane dicarboxylate-based compound represented by the following Chemical Formula 2, and
8 to 20 parts by weight of a citrate-based compound represented by the following Chemical Formula 3,
wherein the weight ratio of the citrate-based compound to the terephthalate-based compound is 0.2 to 0.4,
wherein the weight ratio of the cyclohexane dicarboxylate-based compound to the citrate-based compound is 4 to 5.5,
wherein the weight ratio of the terephthalate-based compound to the cyclohexane dicarboxylate-based compound is 0.64 to 1.5, and
wherein heating loss calculated by the following Mathematical Formula 1 is 2.5% or less:

OG Complex Work Unit Chemistry
in the Chemical Formula 1,
R11 and R12 are identical to each other, and C4-10 alkyl,

OG Complex Work Unit Chemistry
in the Chemical Formula 2,
X1 and X2 are each independently, hydrogen or —C(═O)O—R22, provided that both X1 and X2 are not hydrogen, and
R21 and R22 are identical to each other, and C4-10 alkyl,

OG Complex Work Unit Chemistry
in the Chemical Formula 3,
R31 is hydrogen or acetyl,
R32 to R34 are each independently, C4-10 alkyl,
Heating loss (%)=[(weight of initial plasticizer composition-weight of plasticizer composition after storage at 200° C. for 1 hour)/weight of initial plasticizer composition]×100.  [Mathematical Formula 1]
 
8. A vinylchloride resin composition comprising vinylchloride resin, and the plasticizer composition according to claim 1.
 
12. A molded article comprising the vinylchloride resin composition of claim 8.
 
13. The molded article according to claim 12, wherein the molded article is a wallpaper, flooring, mat, tarpaulin, sealant, artificial leather, toy or coating material of the lower part of automobiles.
